What is the meaning of a "SHRUTI"?

The science of music | DR. Vidyadhar Oke (TEDx, IIT, Gandhinagar)

There are 12 universally identifiable notes ('Swaraprakar' in Sanskrit) in any Octave (Saptak). As we play them from one end on any string, the perception of each of these 12 changes 'only' at 22 points given by nature (See numbers in green in the image below). The sounds produced at these 22 points are the '22 Shrutis' and the 3 types of distances between them are called as 'Shrutyantara' (in Sanskrit, see legend below).
